Piston rod quenching and tempering intermediate frequency heating furnace
The piston rod quenching and tempering intermediate frequency heating furnace is mainly composed of a mechanical conveying device, an intermediate frequency quenching heating module, an intermediate frequency tempering heating module, a closed cooling system, an infrared temperature measuring device, a quenching cooling device, and an intelligent console. The mechanical conveying device consists of a storage table, a turning frame, a nip roller feeding device, and a discharge frame.
The quenching heating, spray cooling, and tempering heating of the piston rod quenching and tempering intermediate frequency heating furnace are all continuous operations; the temperature uniformity is controlled at ±5℃, the hardness after tempering is controlled within 30HRC, the deformation is small, and the resistance after modulation Tensile strength, yield strength, and elongation are 10~15% higher than resistance furnaces.
